Have you ever wondered,
"Just, how clean is this water I'm drinking?" People, these days
worry about what is in their water but end up not doing anything
about it. Usually they extange their water systems or get bottled
water. Still, you can not just go by the quality of the water that
the ad tells you. People can contract very harmful diseases from
drinking from their water systems or strems or lakes. Sometimes we
think, "If I can't see it it's not there" which is completely not
true. Taking precautions in what water you drink could lessen the
risk of getting yourself sick.

I became interested in
this experiment when I was looking through a catalog for experiments.
I knew I wanted to have something to do with water. I found a kit
that tested five different things in the water. So I thought about it
and I talked to my teacher and my mom and they helped finalize my
idea. So I decided to test the water dispensed from the water
machines that are outside of the supermarket. I went around to
supermarkets and collected the water. I, then, tested that water
against distilled water from the Everpure H200 system. The main
reason why I wanted to do this was to see which drinking water is
best for me and my family.
